How do I handle my TM30 registration after returning to Thailand with an ED visa?

After returning to Thailand on a 3-month ED visa, you may need to handle your TM30 registration depending on where you are located. In Bangkok, it has been noted that the immigration office does not enforce TM30 compliance strictly, and it typically does not affect other immigration services such as extensions or residency certificates. However, outside of Bangkok, it is more crucial for your landlord to file the TM30 within 24 hours of your arrival to avoid fines. Many foreigners choose to file it themselves to ensure compliance.
